Applications
Dark Sky Friendly Post Top
Acorn and Lantern-style post-top lighting is a favored option for outdoor areas such as parks and streets. Traditional High-Intensity Discharge (HID) lamps in these fixtures consume a lot of energy and are one of the largest contributors to light pollution. Conventional solutions to switch over to LED fixtures are costly, alters the aesthetics of the fixture, and may still result in significant light pollution. Filamento has developed a retrofit solution that addresses all these issues.
Proven Solution
Filamento’s Post Top Retrofit is a proven solution. The picture to the right demonstrates our low uplight and high light levels on the ground, leading to safer streets due to increased visibility on sidewalks and roads. Details of this installation can be further seen in our Vacaville case study.
98% Reduction in Light Pollution
Filamento’s post top retrofit has low backlight, uplight, and glare (B2-U3-G2). Other LED retrofits, such as ‘corn cobs,’ have high backlight, uplight, and glare (B2-U5-G3). Filamento’s solution removes 98% of the light pollution by directing this otherwise wasted light onto the ground. In a study conducted by Filamento, a metropolitan area with 500 post tops can eliminate up to 3,500,000 lumens of light pollution.
2X More Light on the Ground
The analysis below shows Filamento’s solution delivering 2x more light to the ground than the corn cob LED. It even exceed the HID solution.

House Side Shield
The House Side Shield blocks unwanted light, eliminating light spill. It reduces backlight from ‘B2’ to ‘B1.’ This feature improves comfort for residents by removing intrusive light.
Screw In Lamp Solution
Filamento’s post top retrofit can operate with or without existing ballasts. It can simply screw into the existing fixture to function. It can also bypass the ballast and operate on 100-277V.
Retrofit Fixture Solution
Filamento’s retrofit kit features an adjustable telescoping pole that positions the light at the perfect height within the globe. The retrofit kit is installed with simple tools and operates on 100-277V.
Energy Saving, 2 Year ROI
A study conducted by Filamento shows that a metropolitan area with 500 post tops can save up to $34,000 annually by switching to LED. The typical ROI for a small city is ~2 years.
